Description
"Rørisolasjonselement og fremgangsmåte for fremstilling av elementet." "Pipe insulation element and method of manufacturing the element."
Foreliggende oppfinnelse angår isolasjon for ror, og er særlig aktuell i forbindelse med isolasjon for nedgravde ror som brukes ved fjernvarmeanlegg. The present invention relates to insulation for rudders, and is particularly relevant in connection with insulation for buried rudders used in district heating systems.
Med de "hurtig okende priser på brennstoff og energi er det meget viktig å ta vare på de eksisterende energi- og varme-ressurser. Mens energien var billig ble overskuddsvarme fra industrielle prosesser i blant fort ut i elver og til omgivelse-ne generelt. With the "rapidly rising prices for fuel and energy, it is very important to take care of the existing energy and heat resources. While energy was cheap, surplus heat from industrial processes was sometimes quickly released into rivers and into the environment in general.
Med den vesentlige okning av prisen på brennstoff har det imidlertid blitt stadig viktigere å komme frem til midler for å ta vare på overskuddsenergien fra industrielle prosesser. I de varmere strok på jorden er det mulig å bruke spillvarme fra industrielle prosesser til fjernoppvarming av boliger og arbeidsplasser. For å oppnå dette er det nodvendig å transporte-re varme over betydelige avstander ved hjelp av rorledninger og lignende, og for å ta vare på mest mulig av varmemengden må det anordnes tilstekkelig isolasjon for slike rorledninger. However, with the substantial increase in the price of fuel, it has become increasingly important to find ways to take care of the surplus energy from industrial processes. In the warmer parts of the earth, it is possible to use waste heat from industrial processes for district heating of homes and workplaces. To achieve this, it is necessary to transport heat over considerable distances using rudder lines and the like, and in order to take care of as much heat as possible, sufficient insulation must be provided for such rudder lines.
Bruken av metallror for overforing av varmt vann og andre fluider har lenge vært kjent, og det finnes mange typer isolasjon for slike ror. Med frembringelsen av ekstruderte, fornet-tede polyolefin-ror er det imidlertid blitt muliggjort for-skjellige systemer og teknikker. Istedet for at roret legges i en rekke av rette deler, rulles roret fra en rull og legges ganske enkelt i det onskede forlop. Under slike forhold trengs en annen teknikk for legging av rorene og en annen type isolasjon enn det som hittil er anvendt. The use of metal rudders for the transfer of hot water and other fluids has long been known, and there are many types of insulation for such rudders. However, with the development of extruded, cross-linked polyolefin tubes, different systems and techniques have been made possible. Instead of the rudder being laid in a series of straight parts, the rudder is rolled from a roll and simply laid in the desired course. Under such conditions, a different technique is needed for laying the rudders and a different type of insulation than has been used so far.
Tidligere kjente fremgangsmåter omfattet i prinsippet at rorledningen forst ble dannet, og at den deretter ble dekket med isolasjon på utsiden. Dette ble gjort ved en kombinasjon av innpakking av rorledningen for å hindre korrosjon på dens ytre overflate og deretter dekking av rorledningen med et lag av isolerende material, eller ved ganske enkelt å legge roret ned i en form eller en los fylling av isolasjonsmaterial. Previously known methods included, in principle, that the rudder line was first formed, and that it was then covered with insulation on the outside. This was done by a combination of wrapping the rudder line to prevent corrosion on its outer surface and then covering the rudder line with a layer of insulating material, or by simply laying the rudder down in a mold or a loose fill of insulating material.
Den tidligere kjente isolasjon er kostbar, og er i mange til-feller ikke helt tilfredsstillende, ettersom det gradvise opp-tak av fuktighet i isolasjonsmaterialet naturligvis medforer en forringelse av isolasjonsegenskapene og en tilsvarende okning av korrosjonsproblemene for selve roret. The previously known insulation is expensive, and in many cases is not entirely satisfactory, as the gradual absorption of moisture in the insulation material naturally leads to a deterioration of the insulation properties and a corresponding increase in corrosion problems for the rudder itself.
I henhold til den foreliggende oppfinnelse er det kommet fremAccording to the present invention, it has been achieved
til et rorisolasjonselement som omfatter en langstrakt blokk av isolasjonsmaterial med en ytre overflate og en indre overflate, der den ytre overflate har et lag som er motstandsdyktig mot vann, idet den indre overflate er avgrenset av en hovedsakelig plan flate som rager mellom de ytre begrensninger av blokken og med en eller flere langsgående utsparinger innrettet til å inneholde halve tverrsnittet av et ror eller en slange, to a rudder insulating element comprising an elongate block of insulating material having an outer surface and an inner surface, the outer surface having a layer resistant to water, the inner surface being bounded by a substantially planar surface projecting between the outer limits of the block and with one or more longitudinal recesses adapted to contain half the cross-section of a rudder or hose,
med et langsgående spor parallelt med og i avstand fra utsparingen og i avstand innover fra en forste langsgående kant av den indre flate, samt et langsgående fremspring parallelt med og 1 avstand fra utsparingen og i avstand innover fra en annen langsgående kant av den indre flate, hvorved et par slike ror-isolasjonselementer kan anordnes i forhold til hverandre slik at de indre flater ligger mot hverandre og slik at fremspringet på den ene griper inn i utsparingen på den annen, og slik at utsparingene for rorene sammen avgrenser et rorformet hulrom for roret. with a longitudinal groove parallel to and at a distance from the recess and at a distance inward from a first longitudinal edge of the inner surface, as well as a longitudinal projection parallel to and 1 distance from the recess and at a distance inward from another longitudinal edge of the inner surface, whereby a pair of such rudder insulation elements can be arranged in relation to each other so that the inner surfaces lie against each other and so that the projection on one engages in the recess on the other, and so that the recesses for the rudders together define a rudder-shaped cavity for the rudder.
Fortrinnsvis har fremspringene en bredde som er noe stoi?re enn bredden av det tilsvarende spor, hvorved det kan oppnås en positiv sammenfoyning mellom sporet og fremspringet. De sammen-passende isolasjonselementer kan i sammensatt tilstand forsegles ved hjelp av et tetningsmiddel eller klebemiddel som påfores hvert spor og/eller fremspring for anbringelse av elementene på hverandre, for å holde elementene i riktig innbyrdes stilling. Preferably, the protrusions have a width that is somewhat greater than the width of the corresponding groove, whereby a positive joining between the groove and the protrusion can be achieved. The matching insulating elements can be sealed in the assembled state by means of a sealant or adhesive which is applied to each groove and/or projection for placing the elements on top of each other, in order to keep the elements in the correct relative position.
Det kan anvendes flere utsparinger for ror, idet utsparingeneSeveral recesses for rudder can be used, as the recesses
i et element samvirker med utsparinger på det annet for frem-bringelse av et tilsvarende antall hulrom for ror i. det dannede isolasjonselement. I indre flater og utsparingene i den indre flate er fortrinnsvis dekket med et <£ynt lag av metallfolie for å hindre diffusjon av vanndamp inn i isolasjonsmaterialet. in one element cooperates with recesses on the other to produce a corresponding number of cavities for rudders in the formed insulation element. The inner surfaces and the recesses in the inner surface are preferably covered with a thin layer of metal foil to prevent the diffusion of water vapor into the insulation material.
I henhold til en særskilt utfdreisesform av oppfinnelsen kanAccording to a special embodiment of the invention,
de indre vegger være dekket med en aluminiumfolie som på begge sider er belagt med et lag av polyetylen for å beskytte aluminiumfolien mot korrosjon. Aluminiumfolien kan limes eller på annen måte festes til isolasjonsmaterialet under fremstil-lingen av elementene. the inner walls be covered with an aluminum foil which is coated on both sides with a layer of polyethylene to protect the aluminum foil against corrosion. The aluminum foil can be glued or otherwise attached to the insulation material during the production of the elements.
Den ytre flate av hvert islasjonselement omfatter fortrinnsvis en hovedsakelig plan ytre overflate i avstand fra den indre flate, og har avrundede hjorner som går over i de langsgående sider av hvert element. The outer surface of each insulating element preferably comprises a substantially planar outer surface at a distance from the inner surface, and has rounded corners which merge into the longitudinal sides of each element.
Isolasjonsmaterialet kan være et hvilket som helst passende material med hoy isolasjonsevne. Polyuretan er funnet å The insulating material can be any suitable material with high insulating properties. Polyurethane has been found to
gi en akseptabel isolasjon med rimelige kostnader, og isolasjonsmaterialet kan innpregneres for å nedsette eller hindre inntrengning av vann og for å oke motstandsevnen mot angrep fra skade-dyr. provide acceptable insulation at reasonable costs, and the insulation material can be impregnated to reduce or prevent the ingress of water and to increase resistance to attack by pests.
Utsparingene kan inneholde ror av hvilken som helst tverrsnitt-form, men de er fortrinnsvis halvsylindriske i tverrsnitt i hvert element, slik at et par elementer anbragt mot hverandre avgrenser en langsgående, sylindrisk utsparing for å omslutte ror. The recesses may contain rudders of any cross-sectional shape, but they are preferably semi-cylindrical in cross-section in each element, so that a pair of elements placed against each other define a longitudinal, cylindrical recess to enclose the rudder.
Lengder av isolasjonen kan sammenfoyes innbyrdes ved hjelp av et bånd av polyetylen-folie, som dessuten kan være dekket med asfalt. En forste skjot med bånd kan dannes mellom 2 etter hverandre folgende lengder av isolasjonsmaterial som er anbragt ende mot ende, og det hele dekkes med asfalt, hvoretter et ytterligere lag med bånd av polyetylen/aluminiumfolie påfores skjoten for å forsterke denne. Lengths of the insulation can be joined together using a strip of polyethylene foil, which can also be covered with asphalt. A first joint with tape can be formed between 2 consecutive lengths of insulating material which are placed end to end, and the whole is covered with asphalt, after which a further layer of tape of polyethylene/aluminium foil is applied to the joint to reinforce it.
I henhold til en foretrukket utforelsesform av oppfinnelsen er den ene ende av hvert isolasjonselement utstyrt med en kantflens i lengderetningen, og den annen ende er utstyre med en fals. På denne måte kan flere elementer som ligger ende mot ende fastholdes i forhold til hverandre. Den foretrukne lengde av hvert element er i området 1 meter ettersom dette muliggjor enkel håndtering. According to a preferred embodiment of the invention, one end of each insulation element is equipped with an edge flange in the longitudinal direction, and the other end is equipped with a seam. In this way, several elements that lie end to end can be maintained in relation to each other. The preferred length of each element is in the range of 1 meter as this enables easy handling.
Roret kan være av fornettet polyetylen, og oppfinnelsen omfatter en rorledning i kombinasjon med isolasjonsmaterialet. The rudder can be of cross-linked polyethylene, and the invention comprises a rudder line in combination with the insulating material.
Oppfinnelsen omfatter også en fremgangsmåte for fremstillingThe invention also includes a method for production
av en isolert rorledning, og fremgangsmåten omfatter legging av flere isolasjonselementer ende mot ende slik at det dannes en sammenhengende utsparing for ror i flere elementer, med sporene liggende på en forste side og fremspringene på en annen side, samt legging av roret i utsparingen, og anbringelse av ovre elementer på de elementer rorené er anbragt i, slik at fremspringene på de undre elementer griper inn i sporene i de ovre elementer. of an insulated rudder line, and the method includes laying several insulation elements end to end so that a continuous recess for the rudder is formed in several elements, with the grooves lying on one side and the protrusions on the other side, as well as laying the rudder in the recess, and placement of upper elements on the elements in which the rudder is placed, so that the protrusions on the lower elements engage in the grooves in the upper elements.
Fortrinnsvis er endesammenfoyningene for de ovre isolasjonselementer forsatt i elementenes lengderetning i forhold til sammenfoyningene mellom de undre isolasjonselementer. Etter anbringelse av de ovre elementer fullfores sammenfoyningene ved påforing av bånd og forsegling, og rennen eller groften som rorledningen ligger i, kan fylles igjen på vanlig måte. Preferably, the end joints for the upper insulation elements are offset in the longitudinal direction of the elements in relation to the joints between the lower insulation elements. After placing the upper elements, the joints are completed by applying tape and sealing, and the channel or rough in which the rudder line lies can be filled again in the usual way.
I det fSigende skal oppfiranelsen forklares ved hjelp av utforelseseksempler som viser rorisolasjonselementet- og fremgangsmåten i henhold til oppfinnelsen, under henvisning til de vedfoyde tegninger. In what follows, the invention shall be explained by means of exemplary embodiments which show the rudder insulation element and the method according to the invention, with reference to the attached drawings.

Den ytre overflate er avgrenset av en plan flate 13 i avstand fra den indre flate 12 og et par sider 14 og 14'' . ' som er en fortsettelse av den ytre flate 13 via avrundede kanter 15. Figure 2 shows a cross-section through a pair of joined elements according to the invention. Figure 3 shows in perspective a rough where an insulated rudder line with insulation elements according to the invention is placed. Figures 4 a and 4 b show details of an embodiment of the insulation element. Figure 1 shows an elongated block 10 of insulating material, such as polyurethane, with an outer surface 11 and a substantially planar inner surface 12. The outer surface is bounded by a planar surface 13 at a distance from the inner surface 12 and a pair of sides 14 and 14''. ' which is a continuation of the outer surface 13 via rounded edges 15.
Den indre flate 12 har i det viste eksempel 3 langsgående, parallelle og innbyrdes adskilte utsparinger ,16, som hver har halvsirkelformet tverrsnitt. I nærheten av den ene kant 17 In the shown example 3, the inner surface 12 has longitudinal, parallel and mutually separated recesses 16, each of which has a semicircular cross-section. Near one edge 17

Ved sammenfSyningen klebes tetningsmaterialet 22 i sporet 18 mot den ovre flate av fremspringet 20, slik at de sammenfoyde elementer inneholder en remse med tetningsmaterial cavity for rudder. When joining, the sealing material 22 is glued in the groove 18 against the upper surface of the projection 20, so that the joined elements contain a strip of sealing material
22 på hver side av hulrommene for rorene (se figur 2).22 on each side of the cavities for the rudders (see figure 2).
Ved legging av en rorledning ved fremgangsmåten i henhold til oppfinnelsen graves forst en groft eller renne, og de undre isolasjonselementer 30 legges ned for å motta roret. I henhold til en' utforelsesform legges rorledningen som består av ror 31 av fornettet polyetylen i de sammenhengende utspaa ringer, og de ovre isolasjonselementer 32 anbringes over rorledningen. When laying a rudder line using the method according to the invention, a trench or trench is first dug, and the lower insulation elements 30 are laid down to receive the rudder. According to one embodiment, the rudder line consisting of rudder 31 of cross-linked polyethylene is laid in the connected recesses, and the upper insulation elements 32 are placed over the rudder line.
De ovre isolasjonselementer 32 er fortrinnsvis forsatt en halv lengde i forhold til de undre isolasjonselementer 30, The upper insulation elements 32 are preferably offset by half their length in relation to the lower insulation elements 30,
slik at sammenfoyningene mellom de ovre elementer er forsatt i forhold til sammenfoyningene mellom de undre elementer. Sammenfoyningene er forseglet ved hjelp av bånd av aluminiumfolie dekket med polyetylen, og det hele er dekket med asfalt for å oppnå en vanntett forsegling. so that the joints between the upper elements are offset in relation to the joints between the lower elements. The joints are sealed using strips of aluminum foil covered with polyethylene, and the whole is covered with asphalt to achieve a watertight seal.
Utforelsesformen vist i figur 4 a og 4 b har i en ende en kantflens 31 som rager ut fra enden 10 av elementet langs den ytre vegg 32. Den annen ende 10 merket har en fals 33 langs kanten av elementet, avgrenset av de ytre vegger, slik at når elementene anbringes ende mot ende, styres de på plass i forhold til hverandre ved at flensen 31 på element rager inn i falsen 33 på det neste element. En stav eller remse av tetningsmaterial er fortrinnsvis anordnet på den indre flate av flensen 31, for ved sammenfSyning å bevirke en tetning mellom flensen 31 og endefremspringet 34 som avgrenses av falsen 33. Tetningsmaterialet kan utgjSres av eller inneholde asfalt. The embodiment shown in figures 4 a and 4 b has at one end an edge flange 31 which projects from the end 10 of the element along the outer wall 32. The other end 10 marked has a fold 33 along the edge of the element, bounded by the outer walls, so that when the elements are placed end to end, they are guided in place in relation to each other by the flange 31 on the element projecting into the rebate 33 on the next element. A rod or strip of sealing material is preferably arranged on the inner surface of the flange 31, in order to effect a seal between the flange 31 and the end projection 34 which is delimited by the seam 33. The sealing material can be made of or contain asphalt.
Inngående forsSk har vist at isolasjonselementer i henhold til den foreliggende oppfinnelse muliggjSr en enkel legging av rSrledninger, og bruken av elementene sammen med rSr av fornettet polyetylen gir utmerket isolasjon og medfSrer meget små varmetap. In-depth research has shown that insulation elements according to the present invention enable simple laying of pipes, and the use of the elements together with pipes of cross-linked polyethylene provides excellent insulation and entails very little heat loss.
